Published rates

Scope: Residential
Primary source for this rateResidential annual performance schedule
$300/kW standard; $450/kW underserved; $550/kW low-income
Average measured contribution determines payment over the ten-year participation period. These are alternative customer categories; do not add them together or multiply battery kWh by a kW rate.
Scope: Residential
Primary source for this rateSmall and medium commercial performance schedule
$325/kW in years 1–5; $175/kW in years 6–10
The administrator lists this schedule for customers below 500 kW peak demand. Confirm classification and seasonal settlement in the agreement.
Scope: Commercial
Primary source for this rateLarge commercial performance schedule
$275/kW in years 1–5; $175/kW in years 6–10
The published table labels large commercial above 500 kW peak demand. Ask the administrator to classify a site exactly at 500 kW. Priority C&I customers may also qualify for a $10/kWh enrollment incentive; non-priority customers do not receive that enrollment incentive.
Scope: Commercial
Primary source for this rateThese are published program terms, not a guaranteed payment. Actual earnings depend on measured performance, event counts, and what your aggregator passes through.
Before you enroll
- Utility and account
- An eligible Eversource or United Illuminating electric account in Connecticut.
- Equipment
- Match the exact system and inverter to the administrator's equipment list; final approval requires the applicable DERMS integration.
- Enrollment status
- An eligible contractor must confirm the application date, installation history and customer category. Existing equipment is not automatically approved.
- Dispatch
- New applications from April 1, 2026 use active dispatch with summer and winter performance payments; legacy agreements differ.
- Backup and controls
- Confirm utility controls, storm preparations, reserve settings, performance obligations and backup availability in the agreement.
- Your net payment
- Ask who receives the incentive, what provider or financing charges apply, and when your share is paid. Published rates are not a personal earnings quote.
How the program works
The current design combines an enrollment incentive with ten years of payments based on measured battery performance. New applicants no longer join the former scheduled Passive Dispatch arrangement. Keep an older participant's award separate from an offer for a new project.
Residential and business schedules differ. Select an eligible contractor and the exact approved battery/inverter configuration, then obtain an account-specific application and incentive estimate. A manufacturer name, Connecticut address or directory match does not reserve funding or approve a system.
Who qualifies
- An eligible Connecticut electric account served by Eversource or United Illuminating; another utility's customers need a separate offer.
- An eligible contractor and an approved equipment configuration. Final equipment approval also depends on completing the required DERMS integration.
- Administrator approval of the application, customer category, interconnection and applicable participation agreement before relying on an incentive.
How to enroll
Start with the administrator's eligible-contractor and equipment lists. Have the contractor verify utility service, model/inverter, applicable application date and incentive category. Request the payment recipient, any provider fees, event controls and backup settings in writing before proceeding.
Questions buyers ask
Is this the same as Connecticut ConnectedSolutions?
No. Energy Storage Solutions is the separate route identified for new Connecticut battery applicants. Do not apply the Massachusetts, New Hampshire or Rhode Island ConnectedSolutions rate to a Connecticut project.
Does an existing battery automatically qualify?
No. Ask an eligible contractor and the administrator to assess the installation and application history. The finder identifies a guide to investigate, not approval of an existing installation or a retroactive rebate.
Are the listed incentives my take-home earnings?
They are published program schedules. Actual performance, customer classification and the contract determine payment. Check who receives it, any third-party share and whether the incentive is incorporated into financing or installation pricing.
